Cytogenetic variability of seed progeny from trees of weeping birch (Betula pendula Roth), growingin different ecological conditions
The study of cytogenetic characteristics of weeping birch (Betula pendula Roth) seed progeny was carried out on anthropogenically polluted territories of Voronezh city, and on ecologically «clean» territory. Four groups of seedlings on each territory were revealed. They are «mutable», «low-mutable» and two intermediate groups. The description of cytogenetic characteristics of these groups was made. The results of the study may be used for recommendation on selection of maternal trees producing seeds resistant to unfavorable conditions of the environment.
